Is it really B-Tree based? Apple's HFS+ is B-Tree based and falls
apart (in terms of performance) when you get too many objects in one
FS, which is specifically what drove us to ZFS. We had 4.5 TB of data
in about 60 million files/directories on an Apple X-Serve and X-RAID
and the overall response was terrible. We moved the data to ZFS and
the performance was limited by the Windows client at that point.

The stories I have heard indicate that the name came after the TLA.
"zfs" came first and "zettabyte" later.
